Wishbone with 4 bushings

I have been thinking about building a wishbone with the upper links running in parallel with a peace of tubing welded in between them. The uppers would have a offset bend to them to give it some triangulation but only like 10 degrees per link. It will look more like a H than anything. I don't think the suspension wouldn't have anyway to articulate or way to twist, and act just like a 2-link, but still keep the pinion angle in line through the travel, and be able to set up the instant center as well.    I'm just trying to think out of the box Joe/515CUSTOMS

Similar setups have been done before. When have your wheels on an unlevel terrain, something is going to have to give a little. Take away articulation like that .... and its going to start looking for the weak point. Be it a weld, the frame, the rear end, etc etc etc, something will eventually give out 

On a wishbone with three bushings, how dose it articulate? is it just the one bushing taking all the twist?
